which the following is a speoification, referenee being had to theaecompanying drawin s.

y invention relates to Web roll suqports for'printing'presses and othermac unery Operating upon fabrici. In such machinery, an partioularly inconnection with newspaper presses, the Web roll while being drawn intothe press is carried on a maiidrel held between ehueks or vfreelyrotaiing spindles having heads Which fit into and against the ends ofthe' mandrel so as to center it and support the roll firi'nly withoutinterfering with its freerotation. In high speed newspaper work it isnecessary that the paper roll supports be so constructed that the rollsmay bemounted-n the supports 'quiekly and aecurately, and that/'themanclrels of exhausted rolls he easily removable, so that there will heno appreeiable loss of time in Chang-ing rolls, and, therefore, suchpaper roll supports sre usually so construeted that one of the spindlesis inovahle longitudinally toward and from the other and in the samoaxial line so that the eooperating spindles of a given roll support mayhe separated to release the mandrel of an exhausted roll, or may bebrought together to engage the Inandrel of a. fresh roll; a level; beingprovided for not only moving the lonitudinally movahle spindle, butalso, for oeking the movable spindle in operatve position. Such rollsupports as heretofore oonstructed do not, however. operatesatisfaotorily under all'eonditions, because the range of moveinent ofthe longitudinally mov-able spindle is constant or invariahle, and asthe mandrels are not all of the same length it oeours With more or lessfrequeney that a mandrel is not held tightly and properly eenterebecause of a loose engageinenttherewith of the spindle heads, or, incase the mendrel happen-s to be too long, the morahle spindle cannot heset over far enough to permit the lever to he seourely loclted, and,therefore, there is {longer that the roll-may work loose.

The obgeet ol mypresent 'inventioo is to a roll o f pa Je'r orother.

.port agai'fif' improve the construction of paper roll su Ports of thecharacter mentioned by provi ing a. construction which will ermit therange' of movement of the mora le spindle to he quiokly and aeeuratelyafljusted whenever occasion requires` so that the proper engagement o fthe spintlle heads with the mandrel end the looking of the parts inopera-- tire position may be assured. I aeeoinplish this object asillnstrated in the drawings and herenafter descrihod. What 1 regard asnew is set forth in the claims.

In the aecompanying drawingsf Fig. 1 is an elevation, with some parts insection, and the intermediate portions of the rolls broken away,showing,r a multiple roll {Japer roll stand equipped with roll holdersiaving my improvements applied thereto; and

Fig. 2 is an enlarged longitudinal section of the adjnstable member 'ofone of the roll holders.

In the druwings I have shown my invention applied to o rotary newspaperroll stand arranged to carry three wet rolls, and therefore, providedwith three pairs otroll holders. This will be aparent from on inspectionof Fig. 1 in which 3 indioates the central siiportng shaft of the rollstand which is mounted in saitahle bearings provided in standards 4, 5so as to be variable of rotation. Mounted upon this sli-lift are twobrackets 6, 7 set far enough ::part so that the rolls Sana- V be' placedbetween them, and keyed to the shaft 3 so that they rotate therewith.Eaeh 'oflhese braekets oomprises three pairs of radially-dlsposed arms'10, the

arms ofV the several pairs being;l apart, each pair of arms-of thebracket 5 being opposite :1 pair of arms of bracket 7. The arms of thebracket 7 are'prorided with bearings 11, 12 in which are moun'tedrotaryspindles 13 which havt` no longitudinal inove'ment .in their bearinfls. The spindles'l-l are provided with ehuek theads 14 ada ted toengage one end of the usal. xnandre Which forn'is the center of'thepaper roll, .as shown in Fig. 1'. The arms 9, 10 of the br'aelet'fi areprovided with hear-ing hlocks 15,'16, in which .is monntod a slidingsupport 17" 'whichdoes not rotate i but is eapeble of ,loneitudinal n\remont in its hearngs. Ail`or holding this *alien it is n Vied 'with ei: 3,1 m

ty 18 into whit Key 19 secured to the boariug block 15 by a Screw 20, asshown in Fig. 2, but this may be accomplished in any other suitable way.Mounted in the support 17, which is hollow, is a spindle 21 arranged inaxial alincment with the spindle 13 and having a head 22 adapted toengage the roll mandrel and to cooperate with the corresponding head 14to center and firnily secure the niandrcl in place. Preferably thespindle 21, and also the spindle 13 are mounted in anti-frictionbeerings 23, 2-1, and the spindle 21 is held against longitudinalmovement independently of the support 17 by a rut 25 screwed upon itsinner end, and a cap 26 screwed into the inner end of the support 17.

Tho support 17 is moved longtudinally toward and from the oppositespindle 13 to engage or release the roll by means of a lever 27, whichin the construction illustrated is fulcrumed at its lower end upon apivot 28 carried by a block 29 fixedlyl secured to the sup ort 17, as byscrews 30, this block being p aced atsome intermediate point between thebearing blocks 15, 16 as shown in 2. The intermedi'ate portion of thelevel` 27 is connected with the block 15 by a link 31 which ispivotallyoonnected with the lever 27 by a pirot 32 and is indirectlyconnected with the block 15 by means of a plunger 33 and a pivot 3fl.`The plunger 33 is normally locked in fixed relation to the block 15,but is capable of being moved lonitudinally of itself and in parallelismwith tghe support 17 for the purpose of sccurinr a line adjustment, aswill be heeinafter described, but, for the present, it Will be notedthat when the parts are in the position shown in. full Iines in Fig, 2,if the lever 27 be moved over to the right the pivot 32 will act as afulcrum and the'inner end of the lever will swine to the left, movingthe support 17 and sp1ndle-2 in the same direction until the partsassume the position shown in dotted lines in said figure. 'When theparts are in the latter losition, by moving the lever 27 to the le ttheywill be rcstored to the position shown in full lines. Thus thesupport 17 and spindle 21 may easily be moved toward or from thecorrospondino; spindle 13 on the opposite side of the roll, and therange of movelnent of the spindle 21 and its support will be constant.Fig. `2 shows the operative position of `the spindle 21 in full lines,and it is lockedfin such position by a springlatch 27' monn'ed on the,rlever 27, and having a book 35 which en* gages a pin 36 carried by thelink 31i, Preferably this link is a double one, and the pin 36 is fittedbetween the two members thereof so that it is securely held inposition. 1. Obviously, when the latch-27'l is in its operhtive positionthe lever 27 cannot be actuated, and the spindle 21 cannot move out ofits opeifative position.

While the construction described operates very satisfactorily Withnianrh'els of uniform length, it frequently happens that their lengthvaries, and, therefore, it is necessary that the range of movcment ofthe spindlo 21 and its sup ort 17, that is to say, the extent to whiclithey are moved toward the opposite spindle by the actuation of theoperating lever 27, be adjusted to compensate for such variation, andthat provision be made for making such adjustment easily and quickly inorder that the mounting of the rolls in the stand be not delayed. In myimproved a paratus this is accomplished by ad- ]usting t e plunger 33 tomove the pivot 32 closer to or farther from the opposin chuclc member atthe other side of the rol. For this purpose the plunger 33 is providedwith internal Screw threads in which is fitted the screw threaded end 37of a bolt 38, as shown at the left in Fig. 2. This bolt is mountcd ina`bearing block 39 which is bored concentrically with the plunger 33 andis litted over the outer end of said plunger and secured to the bearingblock 15, preferably by Nl bolts 40 shown in Figi 1. A collar 42 iscarried by the bolt 38 etween the block 39 and the outer end of theplunger so as to prevent outward movement of the bolt 38.

This collar is preferably fitted in the outer end of the bore in whichthe plunger 33 operates, so that it is enclosed by theblock 39. A handwheel 43 is mounted on the outer en of the bolt 38, which is preferablysquare 44 indicates a nut which secures the hand wheel 43 in place.

By this construction, by rotating the handwheel 43 in one direction, thebolt 38 may be turned to force the plunger 33 to- Ward the 'right asviewed in Fig. 2, thereby to:)

the spindle head 22 over to the right,

settin as wil be required to accommodate a shorter mandrel. In likemanner, by reversing the rotation of the hand wheel 43, the spindle head22 can be set back to accommodatela It will be understooti, of course,that instead of placing the adjustable 'spindles at the left-hand end ofthe shaft 3, as illu'strated, they may be placed `*at-the oppositeiend.

For rotating the aihaft 3 I preferably pro- `macbiuery than 'Printingpresses, as it, is 1815 45 driven by suitable igearing actuated by amotorV 46, but this 'has nothing to do 'lwith my present invention,whiclirelates` solely to the devices fcr- It should Ibe understood.therefore,

suitable for use in any situation where a. roll of fabric is to bemounted so as to be cable of unreeling freely.
